I have an expired domain in my niche and the domain has some letters matching mine own, which is kind of an EMD. This expired domain has a good link profile, DA and PA and I plan to 301 it to my money-site. Then build backlinks on this expired site using the keywords of my money-site as anchor. However, before applying this, I must ask opinions. Does this help in SEO? Will building backlinks to this expired domain help my money site to rank? Please let me know, thanks.
